JYE tech dso-068.

I know that JYE tech has their own forum, but it has not been any help. Has anyone here ever put together a JYEtech dso 068? I believe that the 'bob5' board on mine is bad. It is supposed to produce the -5v supply, but I am getting nothing out of it. I would love to get this scope going this weekend. I already have something to troubleshoot with it.

I had similar problem with a DSO130 for JYE tech.  I blew a voltage regulator giving the negative voltage.  When replacing it the scope worked fine.  If this scope came with an instruction sheet you could consult it for voltage checks.  Good luch.
